Abstract

A curved positioning and insertion instrument for inserting a guide wire (50) into the femur has a curved guide tube (2) with a distal end to be placed on the trochanter (41) and/or the medial muscle (45) and a proximal end for inserting a guide wire (50). The instrument also has a holding arm (4) that links the guide tube (2) to a handle (5). A positioning hook fitted with at least one correction bore (7, 8, 9, 10, 12) for receiving the guide wire (50) or another guide wire is arranged at the distal end of the guide tube (2).
This structure makes it possible to easily insert further or additional guide wires (50) relative to a reference guide wire (50).

Claims (17)

1. Curved positioning and insertion instrument for inserting a guide wire (50) into the femur (40), comprising a curved guide tube (2) having a distal end for placing on the trochanter (41) and/or the medial muscle (45) and a proximal end for insertion of the guide wire (50), comprising a retaining arm (4) for the connection between the guide tube (2) and the handle (5), characterized in that a positioning hook (3) is arranged at the distal end of the guide tube (2) and is equipped with at least one correction bore (7,8,9,10,12) for receiving the one guide wire (50) or another guide wire (50).
2. Instrument according to Claim 1, characterized in that the positioning hook (3) has at least four, preferably eight, correction bores (7,8,9,10,12) which are provided in particular on a concentric circle around the guide tube (2).
3. Instrument according to either of the preceding Claims, characterized in that the positioning hook (3) is equipped with at least one guide bore (6) for receiving the one guide wire (50) or another guide wire (50).
4. Instrument according to any of the preceding Claims, characterized in that the design of the positioning hook (3) is nose-shaped and is chosen so that, when placed on the trochanter (41), it comes to rest in the optimum position for the insertion of an opening guide wire (50b) into the femur (40).
5. Instrument according to any of the preceding Claims, characterized in that the guide tube (2) as well as the guide bore (6) are formed in such a way that they can receive both a reference guide wire (50a) and an opening guide wire (50b).
6. Instrument according to any of the preceding Claims, characterized in that the positioning hook has at least one anterior/posterior (7) and/or one medial (8) and/or one posterior/anterior (9) and/or one lateral correction bore (10) in order to be able to tap or drill second or further opening guide wires (50b1) a certain distance away from the first opening guide wire (50b) into the femur (40).
7. Instrument according to any of the preceding Claims, characterized in that the handle (5) is aligned in the insertion position substantially parallel to the frontal femur axis (44).
8. Instrument according to any of the preceding Claims, characterized in that the positioning hook (3) is firmly connected to the guide tube (2).
9. Instrument according to any of the preceding Claims, characterized in that the guide bore (6) extends at an angle (42) of 6°-30°, preferably 7°-20°, in particular about 8°, tangentially to the axis of the guide tube (2) in the region of its distal end.
10. Instrument according to any of the preceding Claims, characterized in that the correction bores (7) extend at an angle to the axis of the guide tube (2).
11. Instrument according to any of the preceding Claims, characterized in that the positioning hook (3) has a particular non slip design for placing on the trochanter (41).
12. Instrument according to any of the preceding Claims, characterized in that the positioning hook (3) has a rounded and narrow nose (11) which holds the positioning hook in the muscle tissue with protection of soft tissue.
13. Method for positioning an opening guide wire (50b) in an intramedullary canal of a femur (40) using an instrument according to any of the preceding Claims, characterized in that the guide tube (2) is loaded with a reference guide wire (50a), the handle (5) of the positioning and insertion instrument (1) is then aligned approximately parallel to the femur axis (44) and with the extension of the intramedullary canal of the femur (40), the positioning hook (3) is placed on the trochanter (41) and pressed thereby with the nose (11) into the medial muscle (45), the reference guide wire (50a) being inserted into the trochanter (41) parallel to the femur axis (44) and as far as possible in the centre of the intramedullary canal, after which the positioning and insertion instrument (1) is removed, the guide tube (2) of the positioning and insertion instrument (1) is loaded with an opening guide wire (50b) and the guide bore in the positioning hook (3) is moved over the reference guide wire (50a) and thus placed again on the trochanter (41), the positioning and insertion instrument (1) accordingly being aligned in order to give the opening guide wire (50b) the correct angle, and in that, if the opening guide wire (50b) is however now not optimally positioned, a correction is carried out with the aid of the positioning and insertion instrument (1), said instrument then being pushed with one of its correction bores over the reference or opening guide wire (50b), and a further, previously loaded opening guide wire (50b1) being inserted in a new position into the trochanter (41) or into the femur (40).
14. Method according to Claim 10, characterized in that the opening guide wire (50b) is present at its insertion point at an angle (42) of 6°-30°, preferably 7°-20°, in particular about 8° relative to the reference guide wire (50a).
15. Method for positioning an opening guide wire (50b) in an intramedullary canal of a femur (50) using an instrument according to any of the preceding claims characterized in that the guide tube (2) of the positioning and insertion instrument (1) is loaded with an opening guide wire (50b), the positioning hook (3) is placed on the trochanter (41) and is pressed thereby with the nose (11) into the medial muscle (45), the positioning and insertion instrument (1) being aligned, according to the design of its positioning hook (3), for giving the opening guide wire (50b) the correct position and the correct angle and in that, if the opening guide wire (50b) is however now not optimally positioned a correction is carried out with the aid of the positioning and insertion instrument (1), said instrument then being pushed with one of its correction bores over the opening guide wire (50b), and a further, previously loaded opening guide wire (50b1) being inserted in a new position into the trochanter (41) or into the femur (40).
16. Set of instruments according to any of Claims 1-12 for methods according to any of Claims 13-15, characterized in that a plurality of position hooks (3) having different characteristics are provided, from which a suitable instrument can be chosen depending on the characteristics of trochanter and soft tissue.
17. Instrument according to any of the preceding Claims, characterized in that the guide tube is curved with a radius of about 300 to 800mm, preferably 500 to 700mm, in particular about 600mm.
